This mod was made in MCreator! also please do not expect this mod to be high quality, as i dont try all too hard. This adds 1 new dimension, 1 new potion, 1 new ore, and 1 new entity (SO FAR), i will continue to make updates every few MONTHS, yes!, MONTHS because im lazy and i dont have too much creativity sometimes!
